How can I do a conditional SQL?

Hello,
How can I make my SQL work conditionally in the WHERE Clause? 
This is the sense that I have:

:is_admin := case when (select ROL_ID from F_ASR_USERS WHERE Trim(USER_IDENTITY) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user))) = 1 then 1 else 0 end;
--IMPORTANT
--IF :is_admin = 1 MUST GET ALL RECORDS (admin)
--IF :is_admin = 0 MUST BRING ONLY CUSTOMER DATA (client)


select 
  FQ7076E3.FEQ70NN as "Numero_Comprobante",
  FQ7076E3.FEQ70NAU2 as "Numero_Autorizacion",
  F0101.ABTAX as "RUC_Emisor",
  to_date(to_date(1900000 + FQ7076E3.FEIVD, 'yyyyddd'),'DD/MM/YYYY') as "Fecha_Emision",
  to_date(to_date(1900000 + FQ7076E3.FEUPMJ, 'yyyyddd'),'DD/MM/YYYY') as "Fecha_Autorizacion",
  FQ7076E3.FETAX as "ID_Fiscal",
  FQ7076E3.FEALPH as "Razon_Social",
  DOCUMENT_TYPE_1,
  sys.dbms_lob.getlength("DOCUMENT_TYPE_1")"Archivo_PDF",
  DOCU.DOCUMENT_FILENAME_1,
  DOCU.DOCUMENT_MIMETYPE_1,
  DOCUMENT_TYPE_2,
  sys.dbms_lob.getlength("DOCUMENT_TYPE_2")"Archivo_XML",
  DOCU.DOCUMENT_FILENAME_2,
  DOCU.DOCUMENT_MIMETYPE_2
 from F0101 F0101,
  F0010 F0010,
  FQ7076E3 FQ7076E3,
  F_ASR_DOCUMENTS DOCU
 where FEDL02='03' 
  and FEQ70DTP='2'
  and FQ7076E3.FECO=F0010.CCCO
  and F0010.CCAN8=F0101.ABAN8
  -- If user is admin it shows all records
  and FQ7076E3.FEQ70NN = DOCU.DOCUMENT_ID(+)
and ( :is_admin = 1 or ( :is_admin = 0 and trim(FQ7076E3.FETAX) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user)) ))

Runs, but does not show data and only works if I remove the variable and the line ( ( :is_admin = 1 or ( :is_admin = 0 and trim(FQ7076E3.FETAX) = Trim(coalesce(sys_context('APEX$SESSION','APP_USER'),user))) ))

yes you can alter index with "alter index" syntax to change.
You can alter index for :-
Rebuild or coalesce an existing index
Deallocate unused space or allocate a new extent
Specify parallel execution (or not) and alter the degree of parallelism
Alter storage parameters or physical attributes
Specify LOGGING or NOLOGGING
Enable or disable key compression
Mark the index unusable
Start or stop the monitoring of index usage

-----You cannot alter an index's column structure.---------

For more details check in the documentation

[ALTER INDEX|http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_1008.htm#SQLRF00805] is beautifully documented.

Thanks,
Karthick.
